Tsujima - Extra Large

Tsujima Natural Sharpening Stone

Our Tsujima natural sharpening stones are from Nagasaki prefecture and are approximately 4000 to 5000 grit. Due to being a little more brittle, the stone it is sealed on all sides with layers of tissue paper and lacquer. Works well as a finisher for both ryoba or kataba style knives or can be used for razors.

There are no inclusions or faults in the Tsujima stones and they easily create a fine slurry. As with many natural stones conservative use of water will bring best results.

Natural Stones

Natural sharpening stones have been used for centuries for knife and tool sharpening. Today with all of the stone mines in Japan closed, natural sharpening stones have become a tightly held commodity. We have managed to secure a small yet reliable quantity of decent sized stones for the Australian market.

High quality natural stones have the following advantages:

Long lasting - these highly prized stones could become a family heirloom that can be passed down

Longer lasting sharpness - the grit in natural stones is more 'random' than synthetics giving varied tooth size on the blade for longer lasting sharpness

If you own a honkasumi knife, natural stones will give you better contrast between the hagane and jigane
